Thanks Amanada. I had seen that post, but given that it was six years old, I was hoping that the limit was changed by now. We are in the process of talking with Apple, so we'll see what they have to say.

Thanks again.

Hi Greg,

There's an older post where they surfaced official Apple documentation/presentation stating that the maximum adv data length they supported was 124 bytes. We imagine those extra 4 bytes might be a header or something else, but they do line up with our findings. The limitation is in iOS, so please contact Apple for the feature request.

Hi Greg,

We are currently understaffed due to the summer vacation period, so delayed replies must be expected. I am sorry about any inconvenience this might cause. I am checking with the team and will update the case once I gather enough information.

Regards,
